摘要： In a GC×GC data processor (23), a modulation time estimation unit (24) creates a one-dimensional chromatogram from chromatogram data items collected by a comprehensive two-dimensional GC, and retrieves a shift time on which a peak position after an entire curve of the chromatogram being shifted in a temporal axis direction coincides with a peak position of the peak on the original chromatogram. Since the resolution of a primary column (12) is low, the same compound is introduced into a secondary column (14) in consecutive modulation times. Accordingly, on the one-dimensional chromatogram, peaks originating from the same compound appear in the respective consecutive modulation times. The interval between the peaks substantially coincides with the modulation time. Therefore, the shift time retrieved as described above is regarded as the modulation time. Thus, the modulation time is automatically estimated from the chromatogram data items, thereby negating the need of user input or capture from an analysis control unit (3).

摘要： A two-dimensional chromatogram creator creates a two-dimensional chromatogram based on data obtained for each of two samples. A chromatogram difference calculator creates a two-dimensional differential chromatogram showing the intensity difference between the two two-dimensional chromatograms. A blob detector detects blobs on each chromatogram. A matching-blob extractor compares the blobs located on the differential chromatogram with those located on each of the two other chromatograms, to extract blobs which can be considered to be located at the same temporal position. If there are two blobs extracted at the same temporal position on the two chromatograms, a normalized value of the intensity difference between the two blobs is calculated, and the line type of the boundary line for indicating the extracted blob on the display is chosen according to that value. Important blobs having significant intensity differences on the two chromatograms being compared can be automatically selected and presented to analysis operators.
